<p>3.2 对比 3.1 有相当大的变化。既对底层逻辑进行了梳理，修复了许多问题，提高了稳定性，也对用户 api 进行了整合。</p>

<h2 id="_1">✅️️ 特性改变</h2>
<h3 id="webpage">📌 <code>WebPage</code>不再自动切换模式</h3>
<p>旧版本中，调用非当前模式独有的方法，会先自动切换模式。比如在 d 模式调用<code>post()</code>方法，会自动切换到 s 模式。</p>
<p>3.2 中，只有显式调用<code>change_mode()</code>时才会切换模式。因此，可以在 s 模式时控制浏览器，不会产生冲突。使用更灵活。</p>
<h3 id="webpage_1">📌 <code>WebPage</code>的标签页对象也可以切换模式</h3>
<p><code>WebPage</code>的<code>get_tab()</code>方法现在返回<code>WebPageTab</code>对象，也能切换模式。创建时默认处于 d 模式。</p>
<h3 id="_2">📌 更改找不到元素时返回值</h3>
<p>旧版本中，查找不到元素会返回<code>None</code>，3.2 版中会返回一个<code>NoneElement</code>对象。</p>
<p>该对象用<code>if</code>判断表现为<code>False</code>，调用其功能会抛出<code>ElementNotFoundError</code>异常。这样可以用<code>if</code>判断是否找到元素，也可以用<code>try</code>去捕获异常。</p>
<p>查找多个元素找不到时，依然返回空的<code>list</code>，这点和旧版本一致。</p>
<p>示例，当我们查找一个不存在的元素时：</p>
<div class="highlight"><pre><span></span><code><a id="__codelineno-0-1" name="__codelineno-0-1" href="#__codelineno-0-1"></a><span class="n">ele</span> <span class="o">=</span> <span class="n">page</span><span class="o">.</span><span class="n">ele</span><span class="p">(</span><span class="s1">&#39;xxxxxxx&#39;</span><span class="p">)</span>
</code></pre></div>
<p>❌ 当前版本用<code>None</code>判断的方式将不可用：</p>
<div class="highlight"><pre><span></span><code><a id="__codelineno-1-1" name="__codelineno-1-1" href="#__codelineno-1-1"></a><span class="k">if</span> <span class="n">ele</span> <span class="ow">is</span> <span class="kc">None</span><span class="p">:</span>
<a id="__codelineno-1-2" name="__codelineno-1-2" href="#__codelineno-1-2"></a>    <span class="nb">print</span><span class="p">(</span><span class="s1">&#39;没有找到。&#39;</span><span class="p">)</span>
</code></pre></div>
<p>⭕ 正确做法：</p>
<div class="highlight"><pre><span></span><code><a id="__codelineno-2-1" name="__codelineno-2-1" href="#__codelineno-2-1"></a><span class="c1"># 用if判断</span>
<a id="__codelineno-2-2" name="__codelineno-2-2" href="#__codelineno-2-2"></a><span class="k">if</span> <span class="ow">not</span> <span class="n">ele</span><span class="p">:</span>
<a id="__codelineno-2-3" name="__codelineno-2-3" href="#__codelineno-2-3"></a>    <span class="nb">print</span><span class="p">(</span><span class="s1">&#39;没有找到。&#39;</span><span class="p">)</span>

<h3 id="_3">📌 部分方法调整</h3>
<ul>
<li>
<p><code>run_js()</code>方法参数顺序作了调整</p>
</li>
<li>
<p><code>darg()</code>和<code>darg_to()</code>方法删除了<code>shake</code>参数</p>
</li>
<li>
<p>元素对象去除<code>wait_ele()</code>方法，改用<code>wait.xxxx()</code>方法等待自身属性改变</p>
</li>
<li>
<p><code>ChromiumPage</code>的<code>to_tab()</code>、<code>close_tabs()</code>、<code>close_other_tabs()</code>方法可接收标签页对象</p>
</li>
<li>
<p><code>ActionChains</code>导入路径改为<code>from DrissionPage.common import ActionChains</code></p>
</li>
<li>
<p><code>Keys</code>导入路径改为<code>from DrissionPage.common import Keys</code></p>
</li>
</ul>
<h3 id="_4">📌 下载默认使用浏览器</h3>
<p>避免不了解 DownloadKit 的用户以为点击后程序没有反应。</p>
<p>现在点击后默认用浏览器下载到程序当前路径，可用<code>download_set.save_path()</code>设置保存位置。</p>
<h2 id="api">✅️️ api 整合</h2>
<p>随着功能的增加，同类 api 也越来越多，比如<code>ChromiumPage</code>以<code>set_</code>开头的方法就有 9 个，元素点击的方式有 5 种。如何这些同类的 api 全堆在一起，会显得十分凌乱。</p>
<p>因此，3.2 版对大量 api 做了整合，避免提示界面越来越臃肿，也增强了开发灵活性。 </p>
<p>旧版的 api 目前还将保留，但将在以后的版本中舍弃。</p>

<h2 id="_7">✅️️ 新增功能</h2>
<h3 id="_8">📌 拦截上传控件填写路径</h3>
<p>之前的版本中，要上传文件须要开发者先在 DOM 内找到文件上传控件，有些经过伪装后实时加载的<code>&lt;input&gt;</code>元素并不好找，有时也会由 js 控制。</p>
<p>新版本中，再也无须费心查找上传控件，只要设置好要上传的路径，然后点击触发文本选择框，程序会自动拦截选择框，并把路径输入到控件，非常便利。</p>
<p>示例：</p>
<div class="highlight"><pre><span></span><code><a id="__codelineno-6-1" name="__codelineno-6-1" href="#__codelineno-6-1"></a><span class="c1"># 设置要上传的文件路径</span>
<a id="__codelineno-6-2" name="__codelineno-6-2" href="#__codelineno-6-2"></a><span class="n">page</span><span class="o">.</span><span class="n">set</span><span class="o">.</span><span class="n">upload_files</span><span class="p">(</span><span class="s1">&#39;demo.txt&#39;</span><span class="p">)</span>
<a id="__codelineno-6-3" name="__codelineno-6-3" href="#__codelineno-6-3"></a><span class="c1"># 点击触发文件选择框按钮</span>
<a id="__codelineno-6-4" name="__codelineno-6-4" href="#__codelineno-6-4"></a><span class="n">btn_ele</span><span class="o">.</span><span class="n">click</span><span class="p">()</span>
<a id="__codelineno-6-5" name="__codelineno-6-5" href="#__codelineno-6-5"></a><span class="c1"># 等待路径填入</span>
<a id="__codelineno-6-6" name="__codelineno-6-6" href="#__codelineno-6-6"></a><span class="n">page</span><span class="o">.</span><span class="n">wait</span><span class="o">.</span><span class="n">upload_paths_inputted</span><span class="p">()</span>
</code></pre></div>
<p>点击按钮后，文本选择框被拦截不会弹出，但可以看到文件路径已经传入其中。</p>
<p>由于此动作是异步输入，须显式等待输入完成才进行下一步操作。</p>
<h3 id="ini">📌 优先读取项目路径 ini 文件</h3>
<p>旧版本中默认 ini 文件存放在 DrissionPage 安装目录下，修改要通过代码进行，给调试带来不便。新版会优先用户项目文件夹下查找<code>'dp_configs.ini'</code>文件并使用，使开发时可方便地进行收到更改配置。项目打包也可以直接打包而不会造成找不到文件问题。</p>
<p><code>easy_set</code>方法中增加<code>configs_to_here()</code>方法，调用该方法可直接把默认 ini 文件复制到当前路径。</p>
<h3 id="_9">📌 查找元素增加或语法</h3>
<p>查找元素增加<code>@|</code>语法，用于或关系匹配多个属性：</p>
<div class="highlight"><pre><span></span><code><a id="__codelineno-7-1" name="__codelineno-7-1" href="#__codelineno-7-1"></a><span class="n">page</span><span class="p">(</span><span class="s1">&#39;@|class=xxx@|name=abc&#39;</span><span class="p">)</span>
</code></pre></div>
<p>或语法<code>@|</code>不能跟与语法<code>@@</code>共同生效。</p>
<h3 id="_10">📌 找不到元素时可抛出异常</h3>
<p>找不到元素时，除了返回<code>NoneElement</code>对象，也可设置直接抛出异常。</p>
<div class="highlight"><pre><span></span><code><a id="__codelineno-8-1" name="__codelineno-8-1" href="#__codelineno-8-1"></a><span class="kn">from</span> <span class="nn">DrissionPage.easy_set</span> <span class="kn">import</span> <span class="n">raise_when_ele_not_found</span>
<a id="__codelineno-8-2" name="__codelineno-8-2" href="#__codelineno-8-2"></a>
<a id="__codelineno-8-3" name="__codelineno-8-3" href="#__codelineno-8-3"></a><span class="n">raise_when_ele_not_found</span><span class="p">(</span><span class="kc">True</span><span class="p">)</span>
</code></pre></div>
<p>该设置是全局设置，设置后整个项目都会生效。</p>
<p><strong>示例：</strong></p>
<div class="highlight"><pre><span></span><code><a id="__codelineno-9-1" name="__codelineno-9-1" href="#__codelineno-9-1"></a><span class="kn">from</span> <span class="nn">DrissionPage</span> <span class="kn">import</span> <span class="n">SessionPage</span>

<a id="__codelineno-9-5" name="__codelineno-9-5" href="#__codelineno-9-5"></a>
<a id="__codelineno-9-6" name="__codelineno-9-6" href="#__codelineno-9-6"></a><span class="n">p</span> <span class="o">=</span> <span class="n">SessionPage</span><span class="p">()</span>
<a id="__codelineno-9-7" name="__codelineno-9-7" href="#__codelineno-9-7"></a><span class="n">p</span><span class="o">.</span><span class="n">get</span><span class="p">(</span><span class="s1">&#39;https://www.baidu.com&#39;</span><span class="p">)</span>

</code></pre></div>
<p>上面的代码会抛出<code>ElementNotFound</code>异常。</p>
